I have decided to try and test battery life of different kernels. I hope these tests will give some insight to whether or not there is a big difference between low voltages (LV) and standard voltage (SV) kernels. For now I have included results (see links) for one kernel and will be including another this evening. As always, comments/feedback wanted.

It has been a few days since I’ve made my last post, and that’s for good reason. I now have a new approach to testing the OC kernels! A very kind developer from droidforums.net, Kill_One, has helped me out by providing a stripped down version of the Sapphire ROM. This ROM contains only what is needed to boot up android and it even blocks all wireless connections right out of the box! Using this ROM will allow me to remove as many variables as possible when benchmarking. The goal is to have less than a .5% variation between 10 runs of a benchmarking app. That said, there may be variables in which I cannot control (think hardware). Also, due to Quadrant’s requirement for an internet connection and my lack there of (due to forced airplane mode), there will be no Quadrant benchmarks performed using the “Clean Room” Sapphire ROM.

Here is the testing procedure:

Install the “Clean Room” ROM via nandroid.

Restore APK’s from SD card.

Benchmark PI

CPU Benchmark

Linpack

System Panel Lite

Autostarts

Drocap2

Battery stats

aLogcat

Shutdown phone, remove MicroSD card, reboot.

Kill all running apps with system panel.

Verify phone is near “braindead” with aLogcat and system panel.

Kill system panel & aLogcat via system/applications/manage applications/running applications. Kill the above two apps and finally the system app itself.

Run the first benchmark, then repeat steps 4-6 before running the next benchmark.

The results should be pretty consistent through 10 consecutive runs of the benchmark. Although I have noticed that Linpack gives the most consistant results. Let me know if you see something you would like added!!!

I finished the revised kernel testing today and have posted the results below. I benchmarked the most common kernels kernels, but I I missed one I will gladly add it to the benchmarks. I have added links to the kernels I used in the benchmarks and will add the Custom Sapphire ROM I used after I ask the developer. I did try the bekit 0.8.4 kernel but it gave the stripped down ROM problems.

Without further ado…. The results.

Note: Charts were calculated by averaging the results for each kernel.

So I found a little time to run some benchmarks for the current LiQuID FroZeN YoGurT ROM. Once I’ve completed testing the ShadowROM 0.0.1 Beta I will begin testing this ROM more thoroughly. Until then…Enjoy!

It has been a hectic week! My infant daughter has had two surguries in the last ten days and, as you could guess, I haven’t slept much either. That said, in the random times I’ve had to myself I managed to get some new benchmarks completed. Soon as time allows I will be posting up the benchmarks for Sapphire 1.1.0 and Liquid Frozen Yogurt. Benchmarks will mirror the setup used for the Shadow ROM. Review.

I’m looking forward to playing with this ROM more, but for now I’m benchmarking ROM’s like hell. I’ll cut straight to the chase, although it is a beta release, I never experienced any problems during my limited time running the ROM. That said, I didn’t push things either. In a future update I’ll address the many features of this ROM and its stability. So for now, enjoy the benchmarks!

Here are the stats (Note: Highest score used for comparisons)

I found a nice explanation of what the VM Heap setting does for performance. I won’t rehash the benchmarks on this one, just give you a link.
